The gears are small and very very smooth with minimal resistance so you need a heavier diff "fluid"
Video of the very first test we did with the center diff at the low grip track at the European Championship (I'll upload it to YouTube as well):

From those pics, it doesn't look like there is a slipper attached to the center diff. If there isn't, are there different diff gears with the car? I read so much emphasis on having to have the slipper set a certain way otherwise the diff gears break, I'm just wondering what happens if/when the slipper is eliminated and there is only a center diff in its place. Thanks in advance.

The center diff "slips" depending on how thick of a fluid or grease you use.
Same applies here as with the slipper.
The thicker the fluid the less diff action you will get and the more strain you will put on the gears.
A normal planetary diff will always send the greatest amount of torque the way of least resistance.
So using an increasingly thicker diff fluid will put you closer and closer to a 50/50 distribution of torque between front and rear.

They held up just fine once again through this weekends Swedish National Championship on very high grip astro run with Schumacher Mini Spike Yellow as control tires powered by an ORCA TX6.5 with added boost
As I've tried to communicate a seamingly endless amount of times on here; there are no problems with the original pinion/bevel gears or internal satellite/planet gears on a properly setup XB4.
We are still running all stock composite gears with no additional shimming and have done so from the very beginning

This way you ensure every surface is coated.
And yes you have to "spoon it out" of the bottle…….but that's of course made way easier if the spoon has a "HUDY approved" label on it

If you want to see how heavy weight diff lube is used watch this video

Are the center diff gears composite?
Is the center diff the same as the front and rear diffs?

After running this car for a few months, these are the things I hope the 2015 car will have:
1. Droop adjustment
2. Floating servo mount
3. Shorty pack option
4. Front and Rear shock towers similar to the Smokem towers
5. Redesigned rear arms so that the lower shock end has two mount points similar to how the front shock end mounts to the front arm

Wish I still had mine. Good no-nonse car that was super easy to setup and very fast. This HB takes forever to make a change to. If you break, might as well go home. No wonder why Ty has his dad come with him. In case he breaks so he can have 4 hands ripping the thing apart to fix it. When it works it's awesome, but Jesus over engineered to a fault.
